Wrong mock generated for the interface with generics

[heww]

Actual behavior A clear and concise description of what the bug is.

For the interface with generics

type Model[T any] interface {
	*T
	TableName() string
}

type Client[T any, P types.Model[T]] interface {
	Create(*P) error
}

The generated mock is like this

// MockClient is a mock of Client interface.
type MockClient[T any, P types.Model[client.T]] struct {
	ctrl     *gomock.Controller
	recorder *MockClientMockRecorder[T, P]
}

// MockClientMockRecorder is the mock recorder for MockClient.
type MockClientMockRecorder[T any, P types.Model[client.T]] struct {
	mock *MockClient[T, P]
}

// NewMockClient creates a new mock instance.
func NewMockClient[T any, P types.Model[client.T]](ctrl *gomock.Controller) *MockClient[T, P] {
	mock := &MockClient[T, P]{ctrl: ctrl}
	mock.recorder = &MockClientMockRecorder[T, P]{mock}
	return mock
}

Expected behavior A clear and concise description of what you expected to
happen.

The argument for the P should be T, not the client.T.

// MockClient is a mock of Client interface.
type MockClient[T any, P types.Model[T]] struct {
	ctrl     *gomock.Controller
	recorder *MockClientMockRecorder[T, P]
}
